1. Millimetre wave waveguide enclosed grid frequency multipliers and imaging
Sammanfattning : The utilisation of the THz spectrum ( 0.3-10 THz ) is hampered by fundamental difficulties in generating power at these frequencies. LÄS MER
2. Interference Mitigation Techniques in FMCW Automotive Radars
Sammanfattning : Radar has emerged as an important sensor for scenario perception in automated driving and surveillance systems. The exponential increase of radar units in traffic and their operating frequency limitations have given rise to the problem of mutual interference. LÄS MER
3. Microwave Power Devices and Amplifiers for Radars and Communication Systems
Sammanfattning : SiC MESFETs and GaN HEMTs posses an enormous potential in power amplifiers at microwave frequencies due to their wide bandgap features of high electric field strength, high electron saturation velocity and high operating temperature. The high power density combined with the comparably high impedance attainable by these devices also offers new possibilities for wideband power microwave systems. LÄS MER
4. Interferometric 3D-shape and deformation measurements using ultra short pulses
Sammanfattning : .... LÄS MER
5. Decision making in airborne surveillance radars employing an electronically scanned antenna
Sammanfattning : .... LÄS MER
